`Application filed December 24, 1907. Serial No. 407,903. (Model.)

To all whom 'it may concern:

, Be it known that LSAMUELM. RHoADs, a citizen of the'United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Hose-Couplings, of which the following is a specification.

This invention relates to hose couplings and has for its objectto provide a simplified and improved coupling for the vpurpose stated which will insure a tight joint and which will enable the sect-ions of a hose to be readily connected and disengaged.

'With the above general object in view, the

invention consists in the novel construction,

combination and arrangement of parts here.- inafter fully described, illustrated and claimed.

In -the accompanying drawings -Figure 1 is a plan view of a hose coupling embodying the present invention. Fig. 2 is a longitudinal section through the same. Fig. 3 is a plan .View of one of'the sections. Fig. 4 isa sectional view of the complemental section. Fig. 5 is a face view of the sections shown in Fig. 3, showing also the'inclosing sleeve. Fig. 6 is aface view of the complemental section.

The hose. coupling comprises an inner section 1 and an outer sect-ion 2 adapted to fit one within the other, as shown in Fig. 2, each of said sections being provided with a threaded or serrated stem 3 upon which the end of a flexible hose is adapted to be placed and held. j

The inner section l tits snugly into the outer section 2 and has its extremity internally rabbeted as shown in Fig. 2 to rece1ve a detachable and renewable gasket 4 which has a cylindrical bore anda` tapering or conical outer surface as clearly shown in, Fig. 2, said gasket being also provided at its extreme end with a circumferential ilange 5 which is adapted to be compressed between the extreme edge of the inner section 1 and an internal annular shoulder 6 formed within the outer sections 2. ln this way a perfectly reliable and tight joint is established between the two intertting members or sections ofj the coupling while the gasket is securely retained in place by one of the sections when the two sections are separated to break the joint.

rlhe inner section 1 is provided with two annular flanges 7 and 8 forming spring seats between which is arranged a coiled spring 9 bearing at one end against one of the flanges and at the other end againstl the othertlanges as clearly shown in Fig. 3.

The flange or spring seat 8 is provided at opposite sides with notches 10 adapted to receive and'interlock with inwardly extending and oppositely arranged lugs 11 and 12 on the inner surface of a ring or sleeve 13 65 -in the form of a hollow cylinder which encircles the flanges 7 and and rests and rides' thereon. One of the -inwardly extending lugs is provided with a hole 14 into which extends a laterally bent extremity 15 70 of the spring 9, whereby said spring is fastened at one end to the sleeve 13 and is adapted to exert its tension on the sleeve 13 and urge said sleeve toward the outer section 2 of the coupling. The interlockin lugs 11 and l2 and the notches 10 referre to, prevent any relative rotation between the inner section 1 and the sleeve 13, and the sleeve is further provided at t-he rear with a knurled bead or annular flange 16 to facili- 89 tate the handling thereof.

The extremity of the inner section 1 is slightly enlarged as shown at 17 and just back lof the enlargement said section is provided'with a circular series of radially pro- B5 jec'ting lugs 18; the opposite side` faces of which are reversely beveled as shown at 19 for engagement with corresponding segment lugs 20 on the extreme edge of the outer section 2 of the coupling, the lugs 20 being 90 located at a suitable distance 4apart to leave spaces 21 through which the lugs 18pass to enable said lugs to be moved behind the segment lugs 20 for the pur ose, of effecting an interlocked engagement b tions 1 and 2. The segment lugs 20 are beveled or chamfered on their inner faces as shown at 22 so as to coperate with the beveled faces of the lugs 18 to produce a wedging or binding fit between the sections. 100

Furthermore, the outer section 2 is provided with an annular lug receiving recess 23 in which the lugs 18 move as they pass behind the segment lugs 20.

The meeting edges of the sleeves 13 and-105 the outer coupling section 2 are provided with interlocking projections 24C and 25 which areheld in interlockin engagement by means of the spring 9 whic acts, as previously stated, to urge the -sleeve 13 toward 110 the section 2. t

To unlock the coupling, the sleeve 13 is etween the secslid back ar'enough to disengage the projections 24 and 25. Then one section of the' cou ling is turned relatively to the other section until the lugs 18 pass out of engagement with the segment lugs 20 whereupon the two sections of the coupling ma be separated. To again couple the sections, the operation just described is reversed.

I claimzi 1. A hose coupling comprising a member provided with spaced flanges 7 and 8 and a circular series of outwardly projecting lugs 18, the lange 8 having notches in its edges, a second member adapted to receive the end portion of the irst-mentioned member and provided with a series of inwardly projecting lugs to pass between and engage behind the lugs of the first-mentioned member, a spring actuated locking sleeve mounted upon the first-mentioned member and having projections to interlock with the notched flange 8 thereof, and terminal interlocking projections between the spring-actuated sleeve and the said member.

2. A hose coupling comprising complemental members 1 and 2, the member 1 having spaced flanges 7 and 8 and a circular series of outwardly extending projections 18, the flange 8 havin f notches 10 and the other member 2 adapter to receive the outer end ,portion of the member l and having inmem er 1 and having an outer flange to come between the outer extremity of said member 1 and the said inner annular shoulder 6', a helical spring mounted upon the lirst-mentioned'member between the annular Hanges 7v and 8 thereof and having an end portion bent outwardly, and a sleeve '18 mounted on the member and inclosing the helical sprin and the spaced flanges 7 and 8 and forme with projections 11 and 12 to enter the notches 10 of the flange 4, one of said projections receiving the outwardly bent end of the helical spring, and terminal interlocking projections between the sleeve 13 and member 2.

In testimony whereof atliX my signature in presence of two witnesses.
